I am trying to add pagination into my project, couldn't find any clear documentation or tutorial.
I have a list of offices
models Office.py
class Office(Model):
name = CharField(_("name"), default=None, max_length=255, null=True)
email = EmailField(_("email"), default=None, max_length=255, null=True)
description = TextField(_("description"), default=None, null=True)
Serializer
class OfficeSerializer(ModelSerializer):
id = IntegerField(read_only=True)
name = CharField(read_only=True)
email = URLField(read_only=True)
description = CharField(read_only=True)
class Meta:
model = Office
fields = ("id", "name", "email", "description")
views.py
@api_view(["GET"])
@permission_classes((AllowAny,))
def offices(request):
instance = Office.objects.filter()[:10]
serializer = OfficeSerializer(instance, many=True)
return Response(serializer.data)
Any help with returning Office list with pagination ?
To enable this pagination style globally, you can set rest_framework. pagination. PageNumberPagination class to DEFAULT_PAGINATION_CLASS and also set the PAGE_SIZE as desired. You can open the settings.py file and add the below configuration settings.
Additionally, switching to keyset pagination will improve the performance of page lookups and make them work in constant time. Django makes it easy to alter its default configuration, giving you the power to build a performant solution for pagination in Django.
Your contexts aren't right and your templates call to the pagination follow the same way, so when you call the pagination object it will will not return a result as you did not use it in your queryset for loop.
Django REST framework (DRF) is a powerful and flexible toolkit for building Web APIs. Its main benefit is that it makes serialization much easier. Django REST framework is based on Django's class-based views, so it's an excellent option if you're familiar with Django.

Pagination is only performed automatically if you're using the generic views or viewsets. If you're using a regular APIView, you'll need to call into the pagination API yourself to ensure you return a paginated response. See the source code for the mixins.ListModelMixin and generics.GenericAPIView classes for an example.
https://github.com/tomchristie/django-rest-framework/blob/master/rest_framework/mixins.py#L35 https://github.com/tomchristie/django-rest-framework/blob/master/rest_framework/generics.py#L166
so I would suggest something like:
@api_view(["GET"])
@permission_classes((AllowAny,))
def offices(request):
pagination_class = api_settings.DEFAULT_PAGINATION_CLASS
paginator = pagination_class()
queryset = Office.objects.all()
page = paginator.paginate_queryset(queryset, request)
serializer = OfficeSerializer(page, many=True)
return paginator.get_paginated_response(serializer.data)
http://www.django-rest-framework.org/api-guide/pagination/
GET https://api.example.org/accounts/?limit=100&offset=400
Response:
HTTP 200 OK
{
"count": 1023
"next": "https://api.example.org/accounts/?limit=100&offset=500",
"previous": "https://api.example.org/accounts/?limit=100&offset=300",
"results": [
…
]
}
Example of settings.py
REST_FRAMEWORK = {
'PAGE_SIZE': 10,
'EXCEPTION_HANDLER': 'rest_framework_json_api.exceptions.exception_handler',
'DEFAULT_PAGINATION_CLASS':
'rest_framework_json_api.pagination.PageNumberPagination',
'DEFAULT_PARSER_CLASSES': (
'rest_framework_json_api.parsers.JSONParser',
'rest_framework.parsers.FormParser',
'rest_framework.parsers.MultiPartParser'
),
'DEFAULT_RENDERER_CLASSES': (
'rest_framework_json_api.renderers.JSONRenderer',
'rest_framework.renderers.BrowsableAPIRenderer',
)
}
